To all whom it may concern:

Be it known that 1,. JOHN T. citizen of the United States, and'a resident of West Philadelphia, in the county of Philadelphia and State of Pennsylvania, haveof the bottle, and adapted to be secured thereto, and a yieldable portion .to extend into the mouth of the bottle.

It is now common practice to use crimped metallic caps to seal bottles, the crimped portion engaging, with intimate contact, the

lower faceof a flange or enlargementon the" bottle neck. These caps havebeen found very eflicient in preserving the contents of the bottle against atmosphericinfluence, but they are usually discarded after "the bottles are primarily opened, which not only results in excessive waste but also permits the contents of the bottle to quickly deteriorate. if common corks are not used to exclude dust orchanging atmosphere. While the crimped metallic caps. now in common ,use may be I used to exclude dust from a bottle, they can not be used to effectively close the bottle againstingress of air, or prevent evaporation of liquid in the bottle.

Therefore, the principalobject of my inventionis to provide bottle caps and stoppers of the character described which will v effectively closetthe openings of the bottles,

and maintain the contents sealed against length of time, and which may also be used to close the'bottles after they have been primarily opened to prevent material evaporation or change of the contents.

Other objects -of my invention will .ap-'

pear in the following detailed description, takenin ponnection with the accompaymg drawing, forming a part of this specification, and in which drawing: v

An adhesive H may be provided if desired, interposed between the members and F,- rifi'dl securing them together.

be substantially like those now in common erring first to the member A, it may:

use, the crimping presenting the shoulders I The stopper member F may be made of any uitable yieldable material, such as cork, rubber, etc, and in its preferred embodiment. includes, in addition to the .hollow cylindrical portion G, an annular flange 4 at the upperportion of said cylindrical pertion, the diameter of-said, flange being slightly greater than the internal diameter of "the member A, so that when the member.

"F is placed into operative relation to the member A, itmust be forced into position with the marginal portion er the flange resting upon the shoulders E, and with the lines of thrust converging toward the upper por-;

,tion B of member A,-as .is clearly shown 1n Fig. 1 of the drawing: If desired, theadhesive H may be interposed between the upaction of the atmosphere, for a considerable per portiono'f member F and the inner face of member B of member A..-

As to the portion G, it may be slightly tapered downwardly to facilitate insertion into the opening of the bottleneck. In

order to-render the cylinder hollow, it has formedthereima recess 5,open'at' the bottom ofthecylinder and which permits the lower portion of the cylinder. to be com pressed, so as to be oval in cross sectioni I In operation, the device isplaced on the "bottle with the cylindrical portion G extending into the opening of the'bottle, after which. the "device is forced downwardly bringing the cylinder into intimate contact fwiththe interior of the neck of the bottle. The top -of the neck may. engage and-compress the flange 4 to assist in sealing the bottle. After the device has been secured ',in place, the crimped portion of the cap is brought into intimate contact with the exterior of the neck, in the well known manner.

It is to be observed that after the capis primarily removed from a sealing position with respect to the bottle, it may be used by inserting the cylindrical portion into .the opening of the bottle and without necessarily bringing'the crimped portion into intimate contact with the neck of the bottle. During the opening of the bottle, the lower portion of cylinder Gmay yield, having a tendency to collapse the cylinder as the member A is pried from operative relation ment in the neck of the bottle to seal the u I claiin:- 1. In combination with "a cap adapted to be secured over a bottle neck, of a resilient stopper carried in the cap and having a de-' pending hollow I portion for binding engagesame, said hollow portion being adapted to be compressed and canted in the neck upon the canting of the cap in removing the same.

2. A combined bottle cap and stopper comprising in combination, a metallic inverted cup-like member with its annular flange crimped; and, a yieldable stopper member adapted to engage in the neck of a bottle, said stopper member carried'by and depending from the interior of said cup-like member and provided with a recess open at its bottom.

8. A combined bottle cap and stopper comprising in combination, a metallic inverted cup-like member with its annular flange crimped; a yieldable stopper member including a hollow cylindrical portion, open at its bottom and adapted to engage in'the neck of a bottle; and,.an adhesive securing said stopper member to the interior of said cup-like member to depend therefrom.-

comprising in combination, a metallic inverted cup-like member with its upper portion plane and its annular flange crimped to provide internal shoulders confrontmg the inner face of said u per portion; and, a stopper member of yiel able material comprlsmg a cylindrical portion to fit in the neck of a bottle, and an annular flange at the upper portion of said cylindrical portion, said flange being of a diameter slightly greater than the internal diameter of the cup-like member and being sprung thereinto to engage the shoulders in the lines of thrust converging toward said upper portion of said cup-like member.
